description The embodiment of the invention discloses a coding method, which is used for improving the repair efficiency and the repair capability of a repair packet. The method provided by the embodiment of the invention comprises the following steps: a sending end device obtains a coding matrix, the coding matrix comprises a target row, the sending end device obtains an available space of the target row, the sending end device receives an original data packet, and if the original data packet is smaller than the available space, the sending end device fills the available space of the target row with the original data packet, if the original data packet is larger than the available space, the sending end device fills the original data packet into the available space of the rows except the target row in the coding matrix, the sending end device determines a repair packet according to the original data packet and the coordinate information of the original data packet, and the repair packet is used for repairing the origina
